Hotel Erbprinz is definitely something of an institution in the Karlsruhe area – and not only for the many conference participants who stay here. This is a foodies' hotspot that prides itself on its stylish interior and excellent cuisine – the domain of Ralph Knebel. The Regensburg-born chef and his team prepare classic fare, drawing on international influences. Select produce is used to create flavoursome creations, which take their cue from the seasons. Incidentally, Ralph Knebel's wife, Jasmina, is also on board producing fabulous desserts in her role as head pastry chef. In summer, the flower-filled terrace is especially delightful and a great spot in which to relax and enjoy a meal on a warm day.
